The section is mainly used to remove broken rice and crude bran shell as well as other impurities, and it can reduce equipment failure,ensure normal operation,lower residual oil yield and solvent consumption.The screening method and wind separation method are usually used in the section.

2.Rice bran softening and conditioning sectionBefore entering the expander,rice bran is heated in advance, temperature of rice bran before expansion is increased,and expansion quality of rice bran is improved.Softening pot is mainly used to soften rice bran,improve its plasticity so as to improve extraction efficiency.

4.Rice bran drying sectionUsing plate dryer to adjust the moisture and temperature to suit for extraction.

5.Extraction sectionOil extraction is an advanced oil production craft, now widely applied to oil plants,and it’s an organic solvent extraction method,oil is extracted from rice bran by contact(soaking or spraying) of solvent and rice bran.

The advantages are as following:

1.high oil yield, low residual oil rate of meal;2.low labor intensity;3.good working environment;4.good meal quality.6.Desolventizing-toasting section The meal from extractor contains 25-35% solvent, for recovering solvent and getting better meal, solvent can be toasted by heating.High material layer toaster is usually applied to remove solvent from meal as well as dry extracted meal; DTDC desolventizer should be used for extracted rice bran meal.7.Evaporation sectionSolvent of mixed oil is vaporized by heating to improve oil concentration of mixed oil, i.e. volatile solvent is separated from nonvolatile matters. Long-pipe evaporator(also named raising film evaporator) is widely used for this section.

8.Steam-stripping sectionUse steam distillation to reduce boiling point of mixed oil,so as to remove trace solvent off at lower temperature.
